Due to the pump shell material used more expensive, poor working conditions, more leakage parts, by simple welding is difficult to achieve the purpose. According to the size and location of infiltration trachoma, different types of cast iron infiltration agent can be used.

1. Through the test method to determine the specific parts of the workpiece leakage, and marked on the mark.

3. Surface treatment. With a steel brush to remove the surface of the oxide layer to be repaired, and then washed with banana water or acetone clean, dry.

4. dipping. With rubber mud in the required infiltration of the site to build a small circle, in order to ensure the concentration of glue, and then continue to glue to the circle, until filled with trachoma.

5. Sealing and curing. According to the above formula to deploy a good epoxy glue, smear on the end of the pores of the adhesive glue, room temperature curing 24h
